Hello, I am not sure if I'm posting this in the right place but I just got Machinarium and love it. I played until the part where you go under into the sewer to flood the room with the card playing goons. I think I hit a bug because I didn't get the 'red screw' in the sewer and flooded the floor. Got a 2nd 'red screw' from the little screwdriver character when he 'spits it out' onto the floor. Then I tried to reload an old saved game to try to get the 'red screw' from the sewer floor but then the screw character didn't spit up a 'red screw.' SInce then, I haven't been able to get the 'red screw' from the character even from other old saved games. I have also restarted the game and rebooted my computer to see if it would clear any temporary data files but that didn't work as well.Please advise.
